Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576298, here are decompositions:

31 + 31576267 = 31576298
37 + 31576261 = 31576298
67 + 31576231 = 31576298
79 + 31576219 = 31576298
97 + 31576201 = 31576298
181 + 31576117 = 31576298
211 + 31576087 = 31576298
307 + 31575991 = 31576298

Showing the first eight; more decompositions exist.
